Stimulating wells in unconsolidated formations

摘要

The present invention provides methods of stimulating fluid production from an unconsolidated formation penetrated by a wellbore while preventing the migration of formation sands with fluids produced from the formation. The methods basically comprise the steps of injecting a hardenable resin composition into a portion of the formation surrounding the wellbore whereby that portion is consolidated into a hard permeable mass, forming an indentation in the wellbore to facilitate the initiation of a fracture in the consolidated portion of the formation, creating a fracture in the formation extending from the wellbore through the consolidated portion of the formation into an unconsolidated portion thereof and depositing hardenable resin composition coated proppant in the fracture whereby the proppant is consolidated into a hard permeable mass.
